I think the important point here is that you still have some anonymity in the sense that your data is processed in the same way as everybody else's. Saying "Google reads your emails" is basically a fear-inducing way of saying "Google scans everybody's emails."

I was trying to point out that some level of snooping by the cloud providers themselves is going on right now. Note that I tried to defend Google's behavior by saying that it is no secret and people are opting into it willfully.
